Critical limits of soil penetration resistance in a rhodic Eutrudox. Author(s): MORAES, M. T. de; DEBIASI, H.; CARLESSO, R.; FRANCHINI, J. C.; SILVA, V. R. da ABSTRACT: Soil penetration resistance is an important indicator of soil physical quality and the critical limit of 2 MPa has been widely used to characterize the soil physical quality, in both no-till... ... Repository: BDPA Publication year: 2014
Soil penetration resistance and Sugarcane rooting under subsuperficial drip irrigation levels. Author(s): RESENDE, R. S.; CINTRA, F. L. D.; PACHECO, E. P.; AMORIM, J. R. A. de; BRANT, R. da S.; SILVA, S. M. da Knowledge of the soil water regime in a dynamic equilibrium condition (steady state) of the emitter?soil?plant system is essential to evaluate the adopted irrigation management, aiming to maximize the... ...

Soil resistance to penetration in an oxisol under integrated and non-integrated grazing systems in southeast Brazil. Author(s): CANEPPELE, B. F.; VALANI, G. P.; OLIVEIRA, P. P. A.; PEZZOPANE, J. R. M.; BERNARDI, A. C. de C.; COOPER, M. In order to learn more about soil physical quality in integrated systems, this study proposed comparing soil penetration resistance in two different depths, 0 - 5 cm and 12.5 - 17.5 cm, in areas under... ...

Soil mechanical resistance to penetration (SMRP) in an Oxisol under different integrated crop/livestock systems (CLS). Author(s): SPERA, S. T.; MAGALHAES, C. A. de S.; FARIAS NETO, A. L. de; WOLF, G.; DORNELAS, K. C. The high values of SMRP indicate reduction of soil water infiltration and high levels of soil erosion. Integrated CLS include forest and pastures. The SMRP of soils managed with CLS can be affected by... ... Repository: BDPA Publication year: 2015
Machine traffic and soil penetration resistance in guava tree orchards. Author(s): SOUZA, W. J. O. de; ROZANE, D. E.; SOUZA, H. A. de; NATALE, W.; SANTOS, P. A. F. dos The study was conducted in irrigated commercial orchards of ?Paluma? and ?Pedro Sato? guavas, which were mapped with a Garmin GPS unit (Cx60). Sixty five sampling points were marked on a 21 x 21 m sam... ... Repository: BDPA Publication year: 2018
Correction of resistance to penetration by pedofunctions and a reference soil water content. Author(s): MORAES, M. T. de; DEBIASI, H.; FRANCHINI, J. C.; SILVA, V. R. da ABSTRACT: The soil penetration resistance is an important indicator of soil compaction and is strongly influenced by soil water content. The objective of this study was to develop mathematical models... ... Repository: BDPA Publication year: 2012
Soil penetration resistance in a rhodic eutrudox affected by machinery traffic and soil water content. Author(s): MORAES, M. T. de; DEBIASI, H.; FRANCHINI, J. C.; SILVA, V. R. da ABSTRACT: Soil compaction caused by machinery traffic reduces crop yields. This study aimed to evaluate the effects of intensive traffic, and the soil water content, on the soil penetration resistance... ... Repository: BDPA Publication year: 2013
Modeling the influence of water content and bulk density on soil penetration resistance. Author(s): VAZ, C. M. P.; MANIERI, J. M.; MARIA, I. C. de; TULLER, M. Repository: BDPA Publication year: 2010
Spatial variability of some biometric attributes of sugarcane plants (variety IACSP93-3046) and its relation to physical and chemical soil attributes. Author(s): GREGO, C. R.; VIEIRA, S. R.; XAVIER, M. A. Tests to evaluate competition between plants, in general do not consider the soil spatial variability, nevertheless, the uniformity rarely is present and can not be assumed without verification. The a... ... Repository: BDPA Publication year: 2010
Variabilidade espacial da resistência à penetração no perfil do solo sob semeadura direta e preparo convencional. Author(s): SANTOS JÚNIOR, J. de D. G. dos; SÁ, M. A. C. de; HURTADO, S. M. C.; REIN, T. A.; SHIRATSUCHI, L. S. Repository: BDPA Publication year: 2008
